The device, whenever a presence (movement) is detected, sends a message over the KNX bus switching on the indicator LED. Sending this message can depend on the level of detected brightness.
The detector is also used to manage movement signals coming from an external source or from any other KNX device.
Thanks to its light sensor, the device enables turning the lights on and off according to the brightness in the room; it is indeed possible to set two types of thresholds, upper and lower, and to carry out different actions according to the settings. These actions enable sending single or cyclical ON/OFF messages over the bus.
The configuration button and the related LED are managed by the configuration software.
The LED that lights up when the detector sends the “presence message” over the bus.

The configuration of the device, physical address and parameters takes place through the ETS software.
